Abstract

PURPOSE: To achieve the improvement of developing and transfer characteristics by moving a non-magnetic cylinder and a permanent magnet roll in the same direction, and moving magnetic toner in the same direction as material layer at the specific speed.
CONSTITUTION: A nonmagnetic cylinder 3 is provided in opposition to the material layer surface formed with an electrostatic latent image and a permanent magnet roll 2 having plural magnetic poles is provided in said cylinder. A magnetic brush is formed by attracting magnetic toner 4 onto the cylinder 3 by the suction force of the magnet roll 2 and the cylinder 3 and roll 2 are relatively moved, whereby the magnetic toner is deposited on the material layer surface and is transferred onto a transfer member. By moving the cylinder 3 and permanent magnet roll 2 in the same direction at this time, the magnetic toner is moved in the same direction as the material layer at up to 100mm/sec. irrespective of the material layer surface moving speed, in the developing part. This enables the developing and transfer characteristics to be improved and the stable image to be obtained.
